Description
A standardized curcuminoid complex from Turmeric (Curcuma longa) rhizomes, containing the three principal curcuminoids (curcumin, demethoxycurcumin, bisdemethoxycurcumin) at 95 percent total content. The product is the generic equivalent of the patented C3 Complex format that has served as the gold-standard curcuminoid composition for clinical research and premium supplement applications.
Bright orange-yellow to deep orange free-flowing powder with characteristic Turmeric aroma. Very limited water solubility; freely soluble in alcohol, DMSO, and oils.
We supply food-grade Curcumin C3 Complex from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include 95 percent Total Curcuminoids (the standard premium supplement grade), 95 percent with defined curcuminoid ratios (the C3 Complex equivalent profile), Bioavailability-Enhanced variants including phytosomal, liposomal, and piperine-combined formats, and Pure Curcumin 98 percent or higher for pharmaceutical research applications.
Bulk and reduced-MOQ shipments. Batch-level COA covering total curcuminoids (HPLC), individual curcuminoid breakdown, residual solvents, heavy metals, pesticides (including specific testing for chromate adulterants), and microbiology.
Introduction
Turmeric has been used in Ayurvedic and Traditional Chinese Medicine for over 4,000 years as an anti-inflammatory and digestive remedy. The principal active curcuminoids were isolated in the 1810s but rose to commercial prominence only in the past three decades as one of the most clinically-studied natural anti-inflammatory ingredients globally.
Industrial production proceeds by hydroalcoholic extraction of dried Turmeric rhizomes, followed by chromatographic purification and crystallization to defined curcuminoid content. The 'C3 Complex' positioning refers to the three principal curcuminoids; the patented original was developed by Sabinsa Corporation and the generic equivalents from competing manufacturers match the same compositional profile.
Recognized as a permitted food ingredient by the U.S. FDA (GRAS), the European Food Safety Authority (E100 food colorant), and equivalent regulators worldwide.
Clinical evidence for curcumin in osteoarthritis, inflammatory conditions, and metabolic markers is among the most extensive for any natural anti-inflammatory ingredient, with hundreds of randomized controlled trials and dozens of systematic reviews. Bioavailability remains the principal commercial challenge, addressed through formulation technologies such as phytosomal and liposomal delivery systems.
Strategic positioning is dominated by joint-support and anti-inflammatory dietary supplements globally, with premium positioning supported by the substantial clinical evidence base.
